Ecu Swap For Better Tuning

[99JDMSTIV6]

Looking for a better tuning option for my 1999 Version 6 STI.

I have seen the Apexi Power FC setups and heard from several tuning sources its a 50/50 shot if it works right or not. I just put in another version 6 motor last week due to the timing jumping, so while it was out I did a few upgrades. Car is getting tuned on Monday 24 July 17 on ECUTEK hopefully the flashes take to my ecu and they don't brick it. I have a spare ecu the ill have on stand by just incase it does. looking for a more reliable tuning solution plus maybe have the capability. I will be hopefully running E85 in a month or so but will be swapping out to bigger injectors.

If you have the money, I'd highly recommend the Haltech ecu for this kind of job.

Another option would be to throw in a USDM ECU in there, adjust all appropriate parts and wiring to the USDM STi, and open source the ECU.

In all honesty, the Haltech PS1000 is a good unit that some of my friends use and it's probably going to the best option for future mapping.

thanks for the heads up. I did ecutek with no issues and made 295 hp on 16psi on a mustang dyno in Connecticut. not bad and it pulls hard as hell all the way to 8k in every gear! absolutely love it now.
